## Meta Platforms is using artificial intelligence to improve its advertising business

Meta Platforms owns three of the four most popular social media networks, including Facebook, Instagram, and WhatsApp, as measured by monthly active users. That those platforms attract 3.4 billion people daily makes Meta a key advertising partner for countless brands. And investments in artificial intelligence (AI) are only strengthening the value proposition.

Meta is using AI to create more engaging experiences across its social media. CEO Mark Zuckerberg says, "AI is significantly improving our ability to show people content that they're going to find interesting and useful." Users spent 5% more time on Facebook and 6% more time on Instagram during the second quarter due to improvements in the underlying recommendation engines.

Meanwhile, Meta made improvements to Andromeda (a machine learning system that powers ad retrieval) and applied the model to Facebook Reels, which increased conversion rates by 4%. Also, the company made improvements to GEM (a machine learning system that ranks and personalizes ads) that raised conversion rates by 3% on Facebook and 5% on Instagram.

Here's the big picture: Adtech spending is projected to grow at 14% annually through 2030, according to Grand View Research. Meta Platforms, the second-largest adtech company, is well positioned to benefit from AI product development. Indeed, Malik Ahmed Khan at **Morningstar** writes, "Meta is a digital advertising juggernaut poised to increase its market share."

## Meta Platforms sees a tremendous opportunity in smart glasses and superintelligence

Meta has established a business unit called Superintelligence Labs, which is focused on model development and product initiatives. The company has invested heavily to build data center infrastructure, with capital expenditures topping $100 billion in the last two years, and is actively recruiting top talent in the field.

The ultimate goal is to develop and monetize superintelligence, which means an AI system that is not only fundamentally smarter than people but also has the capacity to improve itself by learning without human intervention. There are several ways Meta could monetize such a system, but the company is particularly focused on smart glasses.

"Personal devices likes glasses that understand our context because they can see what we see, hear what we hear, and interact with us throughout the day will become our primary computing devices," Zuckerberg wrote in July. "Personal superintelligence that knows us deeply, understands our goals, and can help us achieve them will be by far the most useful."

Importantly, Meta is already the dominant player in the smart glasses market, and its lead is widening. Ray-Ban Meta Smart Glasses accounted for 73% of smart glasses shipments in the first half of 2025, up from 66% in the second half of 2024, according to Counterpoint Research. Investors have good reason to think that trend will continue.

Meta recently introduced its first pair of augmented reality (AR) glasses called Ray-Ban Meta Display, which overlay the real world with a holographic color display on the right lens. The glasses are controlled by a wrist-worn device that tracks finger movements. It integrates with the conversational assistant Meta AI, but future models could integrate with a superintelligence system.

Smart glasses could become a substantial revenue stream for Meta. The augmented reality market is forecast to increase at 38% annually to reach $600 billion by 2030, according to Grand View Research.

## Meta Platforms stock trades at a reasonable valuation

Wall Street expects Meta's earnings to increase at 17.3% annually over the next three years. That consensus estimate is reasonable given that adtech spending is forecast to increase at 14% annually through 2030. But it also leaves room for upside if smart glasses or another superintelligence form factor becomes a material source of revenue.

Regardless, the present valuation of 25.9 times earnings is reasonable even if the forward earnings estimate is spot-on. Those numbers give a price-to-earnings-to-growth (PEG) ratio of 1.5. In that context, Meta is actually tied with Nvidia as the cheapest trillion-dollar stock. So, patient investors should feel comfortable buying a small position today.
